Before referring specifically to the drawings for a detail descriptionof applicants machine, it might be stated that the present machine isdesigned for use by operators of comparatively small ice stations.

The operators of this character of station, under ordinarycircumstances, receive cakes of ice of rather large dimensions from themanufacturer, it being impossible for the manufacturer to ship smallblocks convenient for handling without breakage and increased loss frommelting.

Experience has shown that these smaller ice dealers receive shipments ofice in blocks of conventional size and which, because they are almostuniversally formed by artificial means, are slightly tapered. Thesmaller operators usually score these blocks manually with the wellknownice saws.

Applicant, it is believed, has now provided a machine which can beproduced at such a minimum cost as to permit the smaller dealer to scorethe ice blocks in a semi-automatic manner and by power driven saws. Themachine, because of its simplicity, and efficiency of operation, is ofsuch a practical natureas to be capable of use by the smaller dealers,thus saving not only the manual effort but also the considerable timenecessary in such manual scoring of the ice.

It is admitted that there are machines of more complicated nature whichare sold at a considerably higher price, which accomplish the scoring ofice by means of power driven saws; however, it is repeated that thepresent machine is designed especially for the smaller ice distributor,and now with a machine of such construction he may score the ice upon anexact medial longitudinal line and thereafter score the ice in an exactright angular manner upon a vertical axis without the necessity ofmanually handling the block.

Referring specifically to the drawings, and particularly to Figs. 4, 6and 7, there will be found a gravity type of slide, upon which isadapted to be placed manually a block of ice of a conventional size andshape and of a character which is normally shipped by the manufacturerto the smaller ice dealer. It is advisable that this block be scored topermit facility in breaking the larger block into smaller cakes fordistribution to the cus tomers.

The large block, because of its manufacture in an artificial manner, isslightly tapered. The block is manually drawn or placed upon thestationary slide of a gravity character, he same being referred to as10. This slide 10 is supported upon the cross braces 11 and 1:2, saidcross braces in turn finding their lateral support in the generalframing structure 13 for the entire machine.

This framing support 13 is probably best prising the following portions:Formed in connection with and attached to the slide 10 and immediatelytherebelow are the spaced angle irons 18 and 19. These angle ironsprovide a guide and support for the movable ice slide, which is formedby an intermediate ice supporting bar of considerable length, the samebeing designated 20.

The slidable bar 20 is normally carried by and housed in the stationaryslide 10, the same being supported within the guides 18 and 19 by meansof the plural roller members 21 suitably secured thereto in the axletype manner shown at 22.

It is apparent that this sliding ice support is so secured in the tiltedstationary slide 10 as to'permit extension therefrom by gravity andbecause of the above described roller mounting.

The forward end of the bar 29 has the lateral support 23 fixedly securedthereto in the H manner shown at 24, said cross bar having the flaredextensions 25 which are adapted to'support and hold the ice block 26thereon.

At spaced. distances upon the lower side of the ice supporting bar orslide 20 are stop 1nembers'27. Itmight be stated. at thistime that thesestop members may-have their positions-varied upon the-slide by meansofthe adjustment bolts 28;. The. purpose of these adjustable members willappear later,

although it may be stated: at this time that tensioned position withrespect to the stationary slide 10 by means of the coil spring 31. Latch29 has an upwardly projecting lug 32 depending into the chamber whichnormally houses the projeotible ice support and slide 20. This lug 32 isdisposed normally in the path of the before mentioned stop members 27secured to the slide 20 and therefore prevents projection of the slidefrom the stationary portion 10.

It is apparent, however, that should the operating or contact end 33 ofthe latch be forced downwardly in the position. shown in dotted linesinFig. 8, the slide 20- would be released and permitted to move by gravityout of the stationary ice'slide 10.

In Fig. -7 it will be noted that the slide-2O has been projected, to itsmost extended position. However, once the latch 29 has been operated topermit projection of the slide iii 20 and immediately upon releasethereof, the same again assumes. the full lineposition shown in Fig. 8,it thereforebeing in a position to stop further projection of said slide20, due to contact with one of the following depending lugs 27. r

In summing up the operation of this projectible ice support and slide20,. it will be seen that same is controlled by means of the latch 29and'that movement of the latch permits a determined forward movement ofthe ice block 26, said movement being in,- duced by gravity. t V

This adjustable positioning of theice block upon the projectible slide20, for the pure pose of defining the character .oftransverse score thatis made upon the block. It will be noted in Fig. 5 that a series oftransverse scores have been made in the block 26 and it might be statedat this time that the movement of the block upon the slide 20 iscontrolled in an automatic manner by the operationof the latch 29.

Assuming that the ice slide 20 has reached its furthermost projectedposition shown in 'Fig. 7, the return of the slide to its inactive ornormal position, as shown in Fig. 6, is accomplishedz by means of thecable 34,.which issecured tothe rear end of. the slide at 35. Thiscableis wound upon a drum 36-, to-which the other end of the cable issecured. The drum. is carried upon the shaftr37, which finds lateralsupport at 38 and 39in the be fore mentioned general framing structure13.

The drum. is securedin and wound up and tensioned upon the shaft. 37. bymeansof the coil spring 40, one end of the coil spring being secured tothe drum at 41 and. the other end being secured to the cross brace12at42.

It is believed apparent that the slide is .nor mally maintained in theposition shown. in Fig. 4, but that the weight of the ice and thegravitational movement thereof is sufficient toovercome the tension ofthe spring 40, to

permit projection of the slide 20. However, upon removal of the scored.ice block from the projectible slide, it isobvious that the tension ofthe spring 40 is sufficient to. again wind the cable 34 upon the drum,and there by return the slide to its housed positionin the stationarymember 10.

Within the pit are mounted dual laterally i projecting angles 43 whichare adapted toreceive the forward end of the slide 20 when same has beenprojected to substantially its extreme forward position.- These members43" operate as a support and guide, for the forward end of theprojectibleice slide 20.

Surrounding the stationary slide 10 upon which the ice block 26 is firstplaced, isfound a runway which comprises the followingportions-rl-Lshaped angles 44- and 45 of a substantially oblong form areheld in a spaced but connected and operative relationship by meansoftheplurality of'cross braces4 6. It i'sapparent that these cross bracesare securely attached at either end to the U-shaped angles and" 45'. Theresulting cage-like structure has laterally projecting pivot portions47. and 48 secured by means of brackets 49. and 50 to the beforementioned u-shaped angle 45; Thesepivots'are carried in the laterallydisposed bearing portions 51' and 52, said bearing supports; beingfixedly secured to the before mentioned framing support 13.

int-J ISO one end as at 54 to the runway and at its opposite end to adrum 55, which forms apart of a counterbalancing .mechanism whichincludes the spring 56 coiled upon the shaft 57.

Theopposite end of the coil spring is secured at 58 to a stationarylateral projection 59.

It is quite apparent that any type of counterbalancing mechanism mightjust as well be used, and as stated before, it is used merely to insureease in changing the position of the runway.

Upon the runway is disposed a carriage which comprises a series of crossbraces and framing portions 60. These cross braces as well as connectingsupports therefor, form the platform of the carriage to which. are connected the plural roller members 61. The rollers are secured to thelongitudinal portion 62 to which in turn the before mentioned crossbraces are secured.

It is apparent that the carriage has a rolling and therefore a movableconnection upon the runway. It is readily noted that irrespective of theposition of the runway, the carriage is always maintained in a positionto prevent displacement thereof, this due par ticularly to the placementof the rollers in the U-shaped guide or runway portions 44 and 45.

Upon the carriage is mounted an electric motor 63 adapted for connectionby means of a flexible electric cord to any convenient source ofelectric current. Upon one end of the motor is found a reduction geararrangement, not shown in detail, but being described as 64. The shaft65 projecting from the reduction gear mechanism 64 has secured thereon asmall sprocket 66. A chain 67 connects this small sprocket wheel with alarger sprocket wheel 68 which in turn is mounted upon a stub shaft 69,which finds bearing supports at 70 and 71, said bearing supports beingsecured to the before mentioned movable carriage.

A pinion 7 2 secured to the shaft 69 meshes with a larger pinion 7 3which is secured to shaft 74, the latter being'supported in the dualbearing members 7 5 and 7 6 and also connected to the before mentionedcarriage.

Upon the opposite end of the shaft 74 is found a sprocket wheel 77. Thissprocket wheel engages the chain 7 8 shown in various figures of thedrawings,said chain being fixedly secured in the multiple manner shownat 79 to each of the cross braces 46. The chain is carried in a spacedrelationship with the cross braces 46 by means of the plural blocks 80and their connection with the laterally projecting portions 81 eitherformed integrally with or a part of the chain 7 8 itself.

Upon the opposite side of the electric motor 63 and connected to theprojecting motor shaft is a circular ice scoring saw 82.

Means for mounting the motor 63 and the saw 82 in a tensioned mannerupon the before mentioned carriage is provided in the dual set of cranks83 pivoted to the carriage in the manner shown at 84, the upper ends ofthe cranks 83 being connected as at 85 to the forwardly projecting rods86. These rods 86 project through the upstanding and apertur-ed brackets87 and upon the opposite sideof the bracket and surrounding the rods 86are dual coil tensioning springs 88, which are maintained in a fixedposition upon the rod by means of the brackets 87 at one end, and bymeans of the washers 89 at the other end, the washers being fixedlysecured to the rod by means of the nuts 90 secured to the threaded endsof the forwardly projecting arms 86.

In the above structure is found a mounting for the motor and scoringdevice of such rigidity as to normally permit the scoring of the ice toa depth of approximately 1% inches. However, in case of unusual strainsupon the saw, the motor and the carriage, there may be required atensioned or retractible movement of the saw.

The above described spring take-up mechanism permits lateral movement ofthe saw under such unusual strains and conditions. It is assumed,however, that the mounting of the circular saw is sul'liciently rigidunder normal conditions, to permit the scoring to a depth ofapproximately 1% inches. 1

Now, with. respect to the operation'of applicants ice scoring machine,let it be assumed that the operator has placed a block of ice upon thestationary slide 10. This block has been, we will say, delivered fromthe manufacturer, and is of the conventional size and shape, the samebeing somewhat tapered because of its manufacture in an artificialmanner. The forward end of the block abuts the stopping member 23. Theforward movement of the ice block is prevented in View of the fact thatthe lug 32 on the latch 29 is in engagement with one of the dependinglugs 27 on the movable ice slide 20.

Assuming that the runway is disposed in a position adjacent the blockand upon a longitudinal aXis, the operator then throws on the current,with the result that rotation of the motor through the before mentionedsprockets, chains and pinions, rotates the sprocket Wheel 77, which dueto its engagement with the chain 7 8, operates to move the travelingcarriage about the runway.

Simultaneously with the energization of the electric motor, it is quiteobvious that the circular saw 82 will be rotated at a high rate ofspeed. Because of the reduction gear mechanism 64c, it is also obviousthat the speed of the carriage about the runway is controlled. The speedof this runway may be controlled,

as desired, by the use of various sizes of gear mechanism.

The movement of the carriage, with the rotating circular saw, along theblock of ice, operates to score, the ice upon a longitudinal Lot axis inthe manner shown at 91. Because the 1;.

stantially oblong track and therefore scores i7 the opposite side of theblock in exactly the samemanner. I 7

When the block has been scored upon its longitudinal axis, the operatormerely shuts off the current and the saw and carriage-cease theiractivity. 1

It is apparent that because of the pivotal mounting of the runway'samemaybe disposed in such relationship with the ice block that irrespectiveof the tapered formation thereof, the circular saW willdefine-an exactmedial scoring of the ice block, with'the result'that when said block iseventually split into a plurality of smaller blocks, saidblocks will beuniform in size,-thusovercoming one of the main disadvantages'oficescoring machines.

Now assuming that the operator has made the longitudinal score upon theblock of ice, he then with a minimum of effort, due to thecounterbalancing of the runway, moves the runway to an upright position,asshown' in Fig. 1 of the drawings.

It is repeated hat because of the pivotal mounting of the runway, it ispossible to move the runway and of course the carriage, and ice sawthereon, to a'position to score the block upon a transverse axis atexact right angles to thelongitudinal score, It might be stated at thistime that whenever the runway is elevated, and assuming that the currentis not on, the carriage will assume by gravity a'position at the lowerend of the runway. By

viewing Fig. 1 of the drawings, the function f and purpose of the pit 17is quite obvious.

In order to make the transverse score 92 upon the block 26,it is merelynecessary to energize the electric motor and the carriage will againmake a circuit of theblock, scor ing the ice each time that the carriageand saw pass the block.

It will be remembered that the block is still in its initial positionupon the stationary slide 10. Assuming that the first scorehas beenmade, while the block is in this position, it will be seen thatimmediately following the formation of the transverse score 92 upon theblock, the movable carriage, or rather the motor disposed thereon willstrike the projecting and abutment end 33 of the latch 29 in the. mannershownby dotted lines inFig. 8. Immediately upon the downward move mentof the latch 29, and of course the release of lug 32 from its positionin front of the depending ice slide 20, the weight of the ice block andthe natural gravitational movement thereof permits projection of the iceslide'20 apredetermined distance. We say a predetermined distancebecause as-thecarriage releases the latch 29, same is again immed1atelyreturned 1n a tensioned mannerto 7 its formerposition to contact the"following dependinglug 27 on the slide, and thus-stop theslideinaslightly extended;orl-projected position. 7 I

position to receive It is thusfound that the iceblock has moved apredetermined distance forward. Thecarriage and saW'continue therotational move ment with the result that the block has a second andsubstantiallysimilar transverse score I 93 made thereon. Again, when thecarriage It might be stated at this time that applicant has shown butoneform of automatic means for tripping the slide 20 topermit'forward-movement of the block. It is believed apparent thatvarious characters of automatically'operated mechanism mightjust as wellbe used formoving the block either by gravity or bypowermea-ns to anadvanced g the succeeding transverse scores thereon.

hen the transverse scoring of the block has been'completed the operatormerely elevates the forward end ofitheblock in the main ner shownindottedlines in Fig. 7 and same LS mOVGCl to aposition wheretheoperator may manually break the'block in'to a plurality of cakesof'uniform size and weight.

It might be stated that by scoring the block to a depth of aninchandja'half upon a longitudinal axis, 'theoperator has merely to insertan ice pick in the scores and with a moderate amount of pressure breakthe entire block into a plurality of cakes of a size convenient forhandling as well as sale to the customer.
